One thing I want is longer digital input leads so the box doesn't need to be sitting on top of the project circuit. So, I got the bright idea to create an 18" extension cord with ribbon cable. I thought I might get some crosstalk, but it is worse than I thought.

I am monitoring SPI signals, and the clock signal creates ~30nS spikes on many of the other inputs; even if I have them grounded.

I may try a shorter ribbon cable to see what happens, but wonder if you have any comments about this...

Thanks for the great product, and keep the software improvements coming...
